Configuring VLAN Dynamic Subinterfaces
host1(config-if)#vlan id 201 mac-address 0090.1a01.1234
Create a bulk-configured VLAN range that includes the VLAN ID of the previously
configured VLAN. In this example, the VLAN range 100–250 includes VLAN ID
201.
host1(config)#interface gigabitEthernet 3/1
host1(config-if)#vlan bulk-config test2 vlan-range 100 250
To fully configure the VLAN subinterface, assign an IP address or make it
unnumbered.
host1(config-if)#ip unnumbered loopback 0
Use to configure VLAN as the encapsulation method on an interface.
Issuing this command creates the VLAN major interface.
Example
host1(config-if)#encapsulation vlan
Use the no version to disable VLAN encapsulation on the interface.
See encapsulation vlan.
Use to select a Gigabit Ethernet interface or a 10-Gigabit Ethernet interface.
For information about specifying a Gigabit Ethernet or 10-Gigabit Ethernet
interface, see "interface gigabitEthernet" on page 673 and "interface
tenGigabitEthernet" on page 673.
Examples
host1(config)#interface gigabitEthernet 1/0
host1(config)#interface gigabitEthernet 4/0/1
host1(config)#interface tenGigabitEthernet 4/0/1
Use the no version to remove IP from an interface.
See interface gigabitEthernet.
See interface tenGigabitEthernet.
Use to configure an unnumbered IP interface.
This command enables IP processing on an interface without assigning an explicit
IP address to the interface.
